Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed April 24, 1907. Serial No. 369,934.

To all whom it may concern:

Be it known that I, MAXIME LAUBEUF, engineer, a citizen of the Republicof France, residing at Paris, useful Improvement Relating to the Anchorof a Submarine or Submersible Boat and I do hereby declare the followingto be a full, clear, and exact description of the same.

This invention relates to a new arrangement of the anchor in submarineor submersible boats, whatever may be the form or the nature of thisanchor, anchor plate, grappling iron or other appliance serving to keepthe boat in position by attaching it to an anchorage.

The arrangement consists essentially in providing within the boat avertical tube of suitable form and dimensions, through which the anchorchain passes and in which the anchor is accommodated in its raisedposition.

, The accompanying diagram illustrates the invention.

a is the anchor, the arms or flukes b of which are not very long. It'issuspended vertically in the water-tight tube 0 extending through thehull (Z of'the vessel and terminating below in a cavity in the hull of ashape corresponding with that of a casing which would contain theanchor. The suspending chain extends through the tube and over a chainwheel 6, the slack being accommodated in a tank f on the outer surfaceof the hull. Thus, the weighing or the'casting of the anchor does notnecessitate opening the hull and in no way modifies the condihaveinvented a new and tions of weight and stability of the vessel. To weighthe anchor, the wheel a is turned from within the boat either by hand orthrough a motor.

When the anchor is home, it is stopped by the shoulder g before itsflukes I) touch the hull. It is retained in this position by anysuitable device such as a pin h. For casting anchor the wheel c isunclutched from the driving mechanism and the pin it withdrawn.

In addition to the advantages named, is the fact that the anchor thusaccommodated offers no resistance to the travel of the vessel.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is A submarine or submersible boat having a tube verticallydisposed through the hull of said boat and having an enlarged lower endfor receiving the flukes of an anchor, a chain movable within said.tube, a stopper for en- 23 from the interior of the boat, an anchorconnected with the chain, and means for preventing the flukes of theanchor touching the hull when the anchor is drawn into the en largedlower end of the tube.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
